OVEN OR STOVE.

Specication of Letters Patent.

Patented Sept. 10, 190'?.

Application filed Tune 14,1904. Serial No. 212,554.Y

To all whom it may concern.'

Be it known that I, GIOVANNI MAGNAsoo, a subject of the King of Italy,and a resident of Genoa, Italy,v

have invented certain new and useful Improvements in Baking-Ovens, ofwhich the following is a specification.

This invention relates to improvements in baking ovens and has for itsobject to provide means for facilitating the insertion within the ovenoi the articles to be baked and the removal of the baked productstherefrom. y

The invention is illustrated in the accompanying drawings, in which,-

Figure 1 is a front elevation, partly in section, and Fig. 2 is atransverse sectional View.

Referring by reference characters to this drawing, it will be seen thatthe oven contains one or more horizontal baking chambers, two beingshown for convenience as indicated at b, b.. Each of these chambers haslower and upper tracks or ways c1, c2, upon each of which is removablymounted a frame or carriage c3 adapted to support a plurality of irontables or baking trays d.

As indicated in Fig. l the two carriages are of such length thattogether they equal in length approximately the interior length of thebaking chamber. The frames or carriages in cach chamber are connected byan endless chain or the like, as indicated at g, which passes aroundguide wheels gl .at opposite ends of the baking chamber. Each sprocketchain meshes or engages with sprocket wheel h carried on the shaft hf,projecting to the front of the furnace where it is provided with asuitable hand wheel n2. The oven is provided opposite each chamber withlower and upper doors e, f, movable to uncover an opening of a sulicientsize to enable the plates or trays with the products to be baked to beintroduced into the oven and placed upon the carriages.V By manipulatingthe hand wheel different portions of each carriage may be successivelybrought into line with its respective door opening whereby the entiresurface of each carriage may be covered with baking plates, and in asimilar manner the baked products may be removed from the oven. Thus theentire length of each baking chamber may be iilled with products to bebaked, which may be introduced and re? moved through a single set ofdoors located near the center of the oven.

The oven is designed to be heated from a furnace a located in the lowerpart thereof through suitable passages in the walls surrounding orinclosing the baking chambers, but as these particular passages form nopart of the present invention, a particular description thereof hereinis deemed unnecessary. It is sufficient to say that after reaching thepassage u at the top of the Oven the products of combustion pass down apassage 4v at the back and thence through a horizontal flue y to asuitable chimney notl shown.

Having thus described my invention, what I claim iszl. A baking ovenhaving a horizontally disposed chamber, tracks or guides in said chamberat different levels, a carriage moving on each track, baking platessupported byV each carriage, and chains for moving said carriages,substantially as described.

2. A baking oven having a chamber, horizontal tracks in said chamber atdiierent levels, a carriage on each track occupying approximately onehalf the length of the chamber, baking' plates carried by saidcarriages, and means for moving the carriages in unison, substantiallyas described.

In witness whereof I have hereunto set my hand in,the presence of twowitnesses.

GIOVANNI MAGNASCO.
